Series LTF & LTH Low temperature rise, 80˚C and 115˚C
Series LTF and LTH Transformers are three phase,
low temperature rise, air cooled, general purpose
distribution transformers. These transformers feature
either an 80°C temperature rise or a 115°C temperature rise with a 220°C insulation system and all are
shielded. They are designed for applications where
cool operating temperatures or thermal overload
requirements are demanded.
Thermal overload capability of 15% to 30% is built
in because these units are designed to operate with
a maximum rise of 150°C. This means units with an
80°C rise have a 70°C thermal reserve and units with
a 115°C rise have a 35°C thermal reserve. These
features insure a long life where moderate thermal
or capacity overloads exist.
Features
• NEMA Type 3R, indoor / outdoor enclosure.
• 80°C and 115°C temperature rise units.
• 220°C Insulation system.
• Featuring three phase,

Series ES-31 CE Marked
Series ES Three Phase Encapsulated Transformers are designed to comply with Domestic, North
American, and European Union electrical and testing standards. Series ES are UL and Canadian UL
Listed by Underwriters Labs. In addition, Series ES
are CE Marked, and licensed by the German testing
agency TÜV Rheinland.
Series ES transformers are the answer to your
export needs. With the voltage combinations listed
below, and built in approvals, the ES Series provide
no- nonsense solutions for equipment destined for
the European Community of nations.

Motor Drive Isolation Transformers
Dongan® Motor Drive Isolation Transformers are
specifically designed to meet the requirements of
SCR controlled variable speed motor drives. They
are ruggedly constructed to withstand the high
mechanical forces associated with SCR drive duty
cycles. The double-wound construction isolates the
line from most SCR generated voltage spikes and
transient feedback. These transformers also assist
in reducing some types of line transients that can
cause SCR misfiring.
Features
• Three Phase 3 - 145 kVA.
• Electrostatic shield between windings provides cleaner output voltage and helps to
reduce spikes and transients.
• Wall Mounting brackets are available for sizes
11 kVA through 75 kVA (see page 29).

K-Factor Transformers for Harmonic Loads
Domestic distribution systems and linear loads
operate at the fundamental frequency of 60 Hz.
Harmonic content in distribution systems means
that there are integer multipliers of the fundamental
60 Hz frequency present. For instance, the second
harmonic is 120 Hz, the third harmonic is 180 Hz,
the fourth harmonic is 240 Hz, etc.
Traditionally, linear transformer loads exhibit voltage
and current typically at the fundamental frequency
and generally have little harmonic content. Nonlinear transformer loads, on the other hand, introduce
significant harmonics into a distribution system.
Harmonics are created due to the method in which
nonlinear devices draw current in pulses at the voltage peak of the AC sine wave waveform.
Transformers operating in a distribution system containing significant harmonics will exhibit potentially
serious effects of increased operating temperature.
Additionally, it is common to find overloaded neutral
conductors resulting from the additive effect of third
harmonic and succeeding odd multiple harmonic
current flow (triplen harmonics) as well as circulating currents in the primary, eddy current losses, and
skin effect losses.
Nonlinear loads should be suspected where there is
a presence of switch mode power supplies commonly found in desktop personal computers, printers, mainframes, and other electronic equipment.
Other sources include electronic ballasts, variable
speed AC motor drives, certain fluorescent lighting fixtures, and some types of welders. As existing
distribution systems have these types of devices
installed, harmonic problems multiply!
Harmonic content of a distribution system is indicated by a number called K-Factor. Larger values of
“K” indicate the presence of more harmonics in the
load. Harmonic content of a load may be determined by measurement utilizing a recording analyzing meter. Linear loads have a K-Factor of 1. Switch
mode power supplies have a K-Factor as high as
K-20. Other nonlinear loads have a K-Factor which
varies with the device.
Dongan® K-Factor transformers are specifically
engineered to operate at full load and full harmonic
rating without exceeding the rated insulation system values - effectively neutralizing the dangerous
effects of temperature and circulating currents.
Windings and cores are designed to operate in the
presence of triplen harmonics without overheating
or forcing the core into saturation. These transformers will provide years of trouble free service to large
office buildings, industrial plants, processing equipment and any load with a designated harmonic
content.

Three Phase - Specialty Applications
Three Phase ISOLATED Banks of
2 or 3 Single Phase Transformers
Single phase, stock, general purpose transformers
may be banked to achieve a variety of three phase voltage combinations. These combinations are achieved
by connecting two or three identical 240/480 volt, or
600 volt primary, single phase transformers into three
phase banks. When connected per the diagrams,
these banks provide isolation between primary and
secondary just as a three phase, general purpose
transformer would.
Typically, banks of three single phase transformers are
connected in a Delta Primary and Delta Secondary, or
a Delta Primary and Wye Secondary configuration. The
capacity of the three unit, three phase bank is equal
to the sum of the individual single phase kVA ratings.
For example, three single phase 10 kVA transformers
42
connected in this manner will have a capacity of 3 x 10
kVA - or 30 kVA, three phase.
Conversely, two transformer banks are connected almost solely in an Open Delta configuration. The capacity of the 2 unit, three phase bank is equal to the sum
of the individual single phase kVA ratings multiplied by
86.6% (.866). For example, two single phase 10 kVA
transformers connected in this manner will have a capacity of 2 x 10 kVA x .866 - or 17.3 kVA, three phase.
The configurations shown represent some of the more
popular combinations. Please consult the factory to
obtain information on any configuration not shown in
the charts below.

combinations. These combinations are achieved by
connecting two identical, 240/480 volt primary, 120
x 240 volt secondary, single phase transformers into
three phase, autotransformer banks - much like the

ZIG-ZAG Connected Autotransformers
For developing a neutral from a three phase, 3-wire supply
Three, single phase isolation transformers may be
connected into a three phase “zig-zag” bank to obtain 277 volts by creating a neutral from an existing
480 volt, three phase, three wire service. This neutral can be grounded, allowing a ground fault on any
phase to trip the overcurrent protection. The zig-zag
connection stabilizes the neutral point so that 277
volts will be maintained between each phase and
neutral under unbalanced load conditions, and also
accurately reflects any ground fault condition back
to the supply overcurrent protection.
The bank’s connections require three identical
single phase transformers, each having a 240 x

480 volt primary and a 120 / 240 volt secondary.
The chart below indicates kVA and ampere ratings
for zig-zag banks of three transformers each. For
example, when three 5 kVA transformers are connected per the connection diagram below, the resultant bank provides 17.3 kVA per phase, or 51.9 kVA
for the bank. In this example, 17.3 kVA equals the
maximum continuous load per phase at 277 volts.
In addition to providing a solution utilizing off-theshelf transformers, the zig-zag bank is extremely
economical when compared to a conventional three
phase isolation transformer of similar capacity.
